Noncoplanar antiferromagnetism and quantum topological Hall effect in quarter-electron-filled triangular-lattice K 0.5RuO 2

Transition-metal compounds with triangular lattices exhibit a rich interplay among electron filling, geometric frustration, and electronic correlations, making them an ideal platform for realizing exotic quantum states. Here, using first-principles calculations, we demonstrate that the layered triangular-lattice compou...
